膠管近年(nian)來，開始采(cai)用(yong)(yong)熱(re)(re)塑性(xing)(xing)橡膠，如(ru)熱(re)(re)塑性(xing)(xing)聚氨(an)酯橡膠、聚酯橡膠等。膠管(guan)(guan)(guan)(guan)因(yin)(yin)易彎曲、能(neng)緩(huan)沖、重量(liang)輕及(ji)安裝使(shi)用(yong)(yong)方便(bian)等優(you)點，用(yong)(yong)途(tu)十分廣(guang)泛，如(ru)農業(ye)上排灌農田、港灣疏浚中吸排泥(ni)漿，飛機、坦克(ke)、汽車及(ji)許多(duo)機械裝備中的(de)(de)液(ye)壓(ya)(ya)(ya)系(xi)統(tong)、氣動系(xi)統(tong)、燃油(you)(you)系(xi)統(tong)均(jun)使(shi)用(yong)(yong)許多(duo)膠管(guan)(guan)(guan)(guan)。氣割操作需(xu)要較大的(de)(de)氧(yang)(yang)(yang)氣輸(shu)(shu)出量(liang)，因(yin)(yin)此與(yu)(yu)氧(yang)(yang)(yang)氣表(biao)高壓(ya)(ya)(ya)端連接的(de)(de)氣瓶(ping)（或(huo)氧(yang)(yang)(yang)氣管(guan)(guan)(guan)(guan)道）閥門應(ying)(ying)全打開，以便(bian)保證提供足(zu)夠的(de)(de)流量(liang)和穩定的(de)(de)壓(ya)(ya)(ya)力(li)，防(fang)(fang)止(zhi)低壓(ya)(ya)(ya)表(biao)雖(sui)已表(biao)示(shi)工作壓(ya)(ya)(ya)力(li)，但(dan)使(shi)用(yong)(yong)時壓(ya)(ya)(ya)力(li)突然下降，此時容易發生(sheng)回火，并可能(neng)倒(dao)燃進入(ru)氧(yang)(yang)(yang)氣膠管(guan)(guan)(guan)(guan)而引(yin)起爆炸(zha)(zha)。在保存(cun)、運輸(shu)(shu)和使(shi)用(yong)(yong)膠管(guan)(guan)(guan)(guan)時必須(xu)注意維(wei)(wei)護，保持膠管(guan)(guan)(guan)(guan)的(de)(de)清潔和不受損壞。例(li)如(ru)避(bi)免(mian)陽光照射，雨雪浸淋(lin)、防(fang)(fang)止(zhi)與(yu)(yu)酸、堿、油(you)(you)類及(ji)其(qi)他有機溶劑等影響膠管(guan)(guan)(guan)(guan)質量(liang)的(de)(de)物質接觸。存(cun)放(fang)溫度為-15～40℃，距(ju)離熱(re)(re)源應(ying)(ying)不小于(yu)(yu)1m.如(ru)果由于(yu)(yu)保存(cun)和使(shi)用(yong)(yong)時維(wei)(wei)護不善，或(huo)膠管(guan)(guan)(guan)(guan)使(shi)用(yong)(yong)日(ri)久老化脆硬，這些膠管(guan)(guan)(guan)(guan)內的(de)(de)硫磺質被分解出來，常(chang)常(chang)會因(yin)(yin)此引(yin)起回火爆炸(zha)(zha)事(shi)故。
